SGU Faculty Collaborate On Groundbreaking Cattle Vaccine Research

A group of scientists from St. George’s University, Kansas State University, and the Animal Diseases Research Unit of the U.S. Department of Agriculture have made a groundbreaking development in vaccine research with a new study conducted on cattle.

Bovine Anaplasmosis, a tick-borne disease, wreaks havoc on the cattle industry every year. It’s historically been treated with antibiotics, but in a new study published in PLOS Pathogens, another solution is presented.

“It’s a very significant pathogen. It causes weight loss, anemia, and even death in cattle which results in billions of economic losses in the cattle industry worldwide, whether it’s beef or dairy,” said Dr. Melinda Wilkerson, professor and chair of pathobiology in the School of Veterinary Medicine at SGU. “This group of researchers basically knocked out a gene that was important for growth so that they could immunize cattle.”

The technique is the first of its kind and has potential implications for treating infections in other animals like dogs, or even humans, who are also impacted by tick-borne diseases.

“The research found that when the cattle were exposed to the field organism through the vaccine, it was able to protect the animals from future exposure,” added Dr. Wilkerson. “That is very significant because any vaccines out now are ineffective. This is the start of a new method.”

The Clear Conversations podcast took to the road for a special episode recorded in Nashville during CattleCon, bringing listeners straight into the heart of the cattle industry. Host Tracy Sellers welcomed rancher Steve Wooten of Beatty Canyon Ranch in Colorado for a wide-ranging discussion that blended family history and sustainability, particularly as it relates to the future of beef production.

Sustainability emerged as a central theme of the conversation, a word that Wooten acknowledges can mean very different things depending on who you ask. For him, sustainability starts with the soil. Healthy soil produces healthy grass, which supports efficient cattle capable of producing year after year with minimal external inputs. It’s an approach that equally considers vegetation, animal efficiency, and long-term profitability.

That philosophy aligned naturally with Wooten’s involvement in the U.S. Roundtable for Sustainable Beef, where he served as a representative for the Colorado Cattlemen’s Association. The roundtable brings together the entire beef supply chain—from producers to retailers—along with universities, NGOs, and allied industries. Its goal is not regulation, Wooten emphasized, but collaboration, shared learning, and continuous improvement.
